It contains the following species: [2]
| Image | Common name | Scientific name | Distribution | 
|---|---|---|---|
| Black honey buzzard | Henicopernis infuscatus | the Bismarck archipelago in Papua New Guinea. | |
|   | Long-tailed honey buzzard | Henicopernis longicauda | New Guinea | 
Both species are endemic to New Guinea. Genetic research has found that they are closely related to the Australian endemic square-tailed kite (Lophoictinia isura) and black-breasted buzzard (Hamirostra melanosternon), all sharing a 3-base-pair deletion in the RAG-1 gene. The four species form a monophyletic clade sister to Aviceda within the subfamily Perninae. It has been proposed that they could be united into a single genus, Hamirostra having precedence. [3]
